ACPI
Advanced Configuration and Power Interface. A power
management specification developed by Microsoft, Toshiba,
and Intel. ACPI, which will be part of Windows 98, enables
the operating system to control the amount of power sent
to each device attached to the computer. ACPI will enable
manufacturers to produce computers that automatically
power up as soon as you touch the keyboard. With ACPI,
the operating system can turn off peripheral devices, such
as CD-ROM players, when they are not in use.
